Sealing ring, hub cap system and vehicle

Abstract

A sealing ring includes a retaining portion and a primary sealing lip, the retaining portion extending circumferentially around an axial direction, a radial direction extending radially and perpendicularly away from the axial direction, the primary sealing lip having an extension in the positive radial direction, the primary sealing lip having a pressure side in the direction of the axial direction.

         2 . The sealing ring according to  claim 1 , wherein a deformation space is located between the primary sealing lip and the retaining region, and wherein the deformation space extends rotationally symmetrically, circumferentially about the axial direction. 
     
     
         3 . The sealing ring according to  claim 2 , wherein the primary sealing lip extends in the axial direction and in the radial direction. 
     
     
         4 . The sealing ring according to  claim 3 , wherein the sealing ring has grooves extending in the radial direction. 
     
     
         5 . The sealing ring according to  claim 4 , wherein the grooves extend from the retaining region into the primary sealing lip and/or wherein the grooves have a rounded groove base in a radial plane. 
     
     
         6 . The sealing ring according to  claim 4 , wherein the grooves are arranged on the pressure side of the primary sealing lip. 
     
     
         7 . The sealing ring according to  claim 6 , wherein the primary sealing lip is configured such that when pressure is applied to the pressure side the primary sealing lip is deformed toward the retaining region. 
     
     
         8 . The sealing ring according to  claim 1 , wherein the primary sealing lip extends in the axial direction and in the radial direction. 
     
     
         9 . The sealing ring according to  claim 1 , wherein the sealing ring has grooves extending in the radial direction. 
     
     
         10 . The sealing ring according to  claim 9 , wherein the grooves extend from the retaining region into the primary sealing lip and/or wherein the grooves have a rounded groove base in a radial plane. 
     
     
         11 . The sealing ring according to  claim 9 , wherein the grooves are arranged on the pressure side of the primary sealing lip. 
     
     
         12 . The sealing ring according to  claim 1 , wherein the primary sealing lip is configured such that when pressure is applied to the pressure side, the primary sealing lip is deformed toward the retaining region. 
     
     
         13 . A hub cap system for attachment to a wheel hub of a commercial vehicle, comprising:
 the sealing ring according to  claim 1 ; and   a hub cap having a compressed air feed-through arrangement, that extends in the axial direction.   
     
     
         14 . The wheel hub system comprising the hub cap system according to  claim 13  and a wheel hub, wherein the primary sealing lip abuts or is configured to abut the wheel hub and/or wherein the hub cap is reversibly fixed to the wheel hub via a click lock. 
     
     
         15 . A commercial vehicle, comprising the sealing ring according to  claim 1 . 
     
     
         16 . A commercial vehicle, comprising:
 a sealing ring, comprising:
 a retaining region extending circumferentially about an axial direction; and 
 a primary sealing lip having an extension in a radial direction, wherein the radial direction extends radially and perpendicularly away from the axial direction, and wherein the primary sealing lip has a pressure side in the direction of the axial direction; and 
   a hub cap having a compressed air feed-through arrangement that extends in the axial direction.   
     
     
         17 . The commercial vehicle according to  claim 16 , wherein a deformation space is located between the primary sealing lip and the retaining region, and wherein the deformation space extends rotationally symmetrically, circumferentially about the axial direction. 
     
     
         18 . The commercial vehicle of  claim 17 , wherein the primary sealing lip extends in the axial direction and in the radial direction. 
     
     
         19 . A commercial vehicle, comprising:
 a sealing ring comprising:
 a retaining region extending circumferentially about an axial direction; and 
 a primary sealing lip having an extension in a radial direction, wherein the radial direction extends radially and perpendicularly away from the axial direction, and wherein the primary sealing lip has a pressure side in the direction of the axial direction; and 
   a hub cap system, comprising:
 a hub cap having a compressed air feed-through arrangement that extends in the axial direction; and 
 a wheel hub, wherein the primary sealing lip abuts or is configured to abut the wheel hub and/or wherein the hub cap is reversibly fixed to the wheel hub via a click lock. 
   
     
     
         20 . The commercial vehicle according to  claim 16 , wherein a deformation space is located between the primary sealing lip and the retaining region, and wherein the deformation space extends rotationally symmetrically, circumferentially about the axial direction.
